Title: Ultrafine particles prodn. and recovery by vapour deposition - where particle carrier is moved within gas phase in chamber and ultrafine particles are evaporated by heating vaporisable material
Inventor: NISHIWAKI AKIRA
IPC: B01J3/00
Filed: 1990-10-08
Abstract: To produce and recover ultrafine particles by vapour deposn. such as organic ultrafine photo conductive particles for electrophotographic photoreceptors, the particle carrier is moved within a gas phase in a section of a chamber and the ultrafine particles are evaporated by heating the material which can be vapourised to be laid on the moving carrier. The laid particles are collected while further particles are deposited on another part of the carrier. The pref. material is an organic dyestuff suitable for use as an electrophotographic receptor, such as a pigment of the anthranthron type. The deposited particles are collected by a scraper blade, a brush, by suction, by stripping, through a blanket or roller. The material is evaporated at a temp. of more than 80 deg.C. and the particle-charged content is cooled at less than 10 deg.C. The chamber section is evacuated to 10-2-102 Torr. The ultrafine particle size is from 10 Angstroms to 1000 Angstroms or several times 20000 Angstroms. ADVANTAGE - The method gives a high prodn. and recovery rate of ultrafine particles, with high grade particle characteristics.

Patent DE-4100989-A1 (DE)
Inventor: JURMANN ALEXANDER DIPL ING
IPC: C21D1/773
Filed: 1991-01-15
Abstract: The invention relates to the heat treatment of workpieces in a vacuum furnace, using hydrogen. For convective heating and for high-pressure gas-quenching of the workpieces, usually nitrogen and helium are used. To achieve shorter heating and/or cooling times, the use of hydrogen is desirable, but this raises safety engineering problems. The risks are here considerably reduced if, according to the invention, a space which surrounds at least a part of the vacuum furnace and is insulated gas-tight is flushed with an inert gas and continuously checked for its hydrogen content and oxygen content.
